LUBRICATOR.

SPECIFICATION forming part of Letters Patent No. 320,704, dated June 23,1885.

' Application filed April 10, 1885. (No model.)

To all whom it may concern:

Be it known that I, PHILLIP L. SOHMITT, of Quincy, in the county ofAdams and State of Illinois, have invented a new and useful ImprovementinLubricators; andIdohereby declare that the following is a full, clear,and exact description of the same.

My invention is an improvement upon lu bricator-cupsof that class inwhich the oil is IO fed to the engine by displacement caused by thecondensation of the steam conducted from the boiler-space into theoil-cup. The displaced oil is thence conducted to the working parts ofthe engine.

I 5 The object of my invention is to render the parts more compact andto simplify the construction.

In the accompanying drawings, Figure 1 shows an elevation of theimproved cup. Fig.

2 is a'detail sectional view of the drip-tube and its valve, showing,also, the connection with the equalizing-pipe. Fig. 3 is a detailsectional view. Fig. 4 is a side elevation, with the reservoir insection, and the branched stem also in section.

In the drawings, A represents the oil-reservoir, of the ordinarycylindrical form, but cast without any bosses or projections. It issupported upon a branched stem, B, which is screwed into any suitablesteam-connection,

whereby steam may be taken from the boilerspace and oil may betransmitted to the parts which are to be lubricated. The stem B isthreaded at its lower end for this connection.

It has two branches, at b, the branch a being solid and supporting thereservoir A. The branch bis tubular, and is connected with the glasstube, which forms a sight-feed. The lower end of the glass tube 0 isconnected by suitable coupling-pieces, d e, and packing to the branchI). The upper end of the tube is connected by a coupling, f, and packingto a cap, G. This cap G has a stem, 9, screwed into the body of thereservoir, near its upper end, and through this stem and the cap G apassage is formed for the displaced oil to a drip-nozzle, ii, in theglass tube. It will be understood that the stem forms communicationbetween the reservoir and the glass tube. At the junction of the passagein the branch b with the tube leading into the steamspace is a pipe, D,inserted into a nipple, k, cast into one piece with the stem B. Upon theother side of the stem, directly opposite the connection of the pipe D,but seated a little lower, is a valve, E, which is adapted to close thecommunication between the cup and the steam-space below the junction ofthe passages in the branch I) and the pipe D, so that by. closing thisone valve steam may be wholly 6o shut off from the cup, and the flow ofoil excluded at the same time, and this single valve takes the place oftwo valves heretofore used. The cap G is provided with aregulatingvalve,- F, and it also has an equalizing-pipe, Z, connectedwith it, and also connected at the other end with the pipcD by means ofan ordinary T-coupling. The upper end of the pipe D is bent over andcoiled about itself to form a condenser. The end is then carriedlaterally, and is connected by a suitable coupling to a plug, H, whichis connected to the upper end of the reservoir, and this plug is thefilling-orifice, provided with an ordinary screw-stopper. At the bottomof the reservoir 7 5 is a drain-cocl m, for drawing ofl the water ofcondensation.

In the operation of the machine the steam is introduced through the stemB and rises through the pipe D, in the coil of which it condenses andflows as water of condensation into the cup, where it displaces the oilin the ordinarymanner. The oil displaced runs off through the stem 9into the cap G and drops from the nipple through the glass tube, flows 85 down through the branch 7) into the steampassage, and thence to theparts to be lubricated. Part of the steam from the pipe D is diverged tothe cap and equalizes the press ure in the passage between the oil-cupand 0 the glass tube, thereby aiding to keep those passages warm andprevent any obstruction therein.

I claim as my invention- 1. The combination, in a lubricator, of a 5central stem, B, adapted to be connected with the steam-space branches a1), extending laterally from said stem, the branch a being solid andadapted to support the reservoir, and the branch I) being adapted tosupport the rco adapted to support the reservoir, and branch 7 1),adapted to support the glass tube, the pipe D, extending from the stem Bto the upper end of the reservoir, with the branch pipe Z between saidpipe D and the glass tube, all substantially as described. I

4. The combination, in'a'lubricator, of the 20 reservoir, the steam-pipeD, adapted to be connected to a plug, I-I, said plug having a passageextending through one part thereof for the admission of steam and asecond passage for the admission of oil to the reservoir, sub- 25stantially as described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
